Side bearing



Jan. 29, 1935. E. w. WEBB SIDE BEARING Filed June 5, 1933 n w i Mwm T E NWN E M 5 v 7 r N i an I M 6 two side walls of the housing and rests on a tread plate T. This tread plate may be provided with upwardly projecting spaced tread surfaces which diverge sharply from the center of the plate or the plate may be provided with any well known type of tread surface, so as to cause centering action of the roller R on the tread plate. The

left end'of the tread plate, as tviewed in Figs. .1- and 2 of the drawing, is provided with-projectin'g' spaced lugs 30 which overlie the lugs 15 and underlie the rib 16 with freedom for considerable.-

vertical movement between the lugs 15 and the rib 16. The other end of the tread plate T is -pro-z vided with a central outwardly projecting mg 31 which underlies the rib,.1 8,wit h;'1reedoni for,

considerable vertical movementrelative thereto. To prevent longitudinal movement of the tread plate T to the left, as viewecl in *Figs.Fahd 2; when it is in position within the h0using H, the tread plate is provided at its left end with "notches forming shoulders 322to :engage short vertical Jobs-33 running between'the-iends of 'thelrib 16 4 and underlie the tread plate T.

. In :assembling athe side :bearing, the roller,

is first inserted betweenthe twoside walls 6 and '7 "and the pincpeninginthe. roller is alined withthe'two'openings 27.28,!!(1128. I Thepin' 29 is :then

passed through the pin opening 28, and "through the'openingfin the roller R. to be received at one end within the circularrecess joiningcthe recessin thebulged portion 26. The roller and pin are then raised upwardly above: the-level of the. two

openings 27 'and:28. -1=The tread plate-T is then insertedin placezthrough theopening in thebottom of the'housin'g-"H to take its normal' position below the roller 'R -with the lugs: .30 of; the tread plate positioned to overlielthe lugs 15.-and to underlie the'e'nds of the rib 16, The-housing H may; then be secured to the truck bolster 4, whereupon the desired'number' orshims S may be inserted from the right end of the housing, as viewed in Figs. 1 and 2-,' through the'opening 1'7 to'underlie the tread' plate T and thereby 'carryptheupper' portion" or the'roller B, to the proper'level above the-housing H for properuse.

located as shown in the drawing, whereupon-the" eye 25 of the guard G may be positioned so that the bolt 20 will'ru'n' therethrough and-the'lower' end of the guard 'maybe dropped into the guides 23. The upper end-of the'guard may then be swung inwardly to -theposition shown in'the drawing, so-thatit underlies the lip 22. As this'is done, thepin 24 of the guard will be"received' within the opening fi of, the truck bolster 4 and' the guard will wedge down'in theguides 23. The l 21 i en. i .ht i h eu n h e bearing will be ready foruse;

When in [e the guaraewiu; o'fcourse, pre

, vent removal-oi the shims s fipm the housing:

Even if through constant jar on the parts the nut 21 should loosen somewhat; thelip 22 will prevent the guardfroni raising upwardly -to permit r'emoval of the shims. Even if the nut 21' should come way ofiof the bolt 20", thereis very little likelihoodthat the guard 'will" raise *sufliciently V The bolt 20f'if not previously inserted in position, may'thenbe' endof the guard G may be swung outwardly beyond-the lip 22 from the end wall 9 and then slid upwardly; Additional-shims may then be insertedbeneaththe tread plate T through the openingl'? to raise the height of the roller R or, if desired, one or, more shims may be removed from underneathtif' tread plate to decrease the fheight of the roller.

It will be seen that an exceedingly simple side bearing--has -been provided-which can be adjusted from time to time by use of shims without difliculty' and wherein the shims. cannot be removed accidentally.

P "It Willi-of "course, be understood that 'various rangement and proportions ot the various parts invention.
